Objective:
To observe the effect of lumbar disc herniation treated with acupuncture at different time intervals.
Methods:
A total of 180 patients of lumbar disc herniation were randomized into an observation group 1, an observation group 2 and an observation group 3, 60 cases in each one. All patients were treated with acupuncture at Jiaji L3-L5 (EX-B 2), Huantiao (GB 30), Weizhong (BL 40), etc. And then KWD-808 electroacupuncture instrument was connected, time intervals of acupuncture were once every day, once every 2 days and once every 3 days, 3 weeks were provided. At 1-week, 2-week and 3-week treatment, the visual analogous scale (VAS) and Japanese Orthopedics Association (JOA) scale were observated, and the effects were evaluated.
Results:
The effective rates in the observation group 1 and the observation group 2 were 96.7% (58/60) and 95.0% (57/60), there was no significant different between the two groups (P>0.05), which were superior to 88.3% (53/60) in the observation group 3 (both P<0.01). The VAS score in each group decreased to different degrees at 1-week, 2-week and 3-week treatment compared with those before treatment (all P<0.01), there was no significant different between the observation group 1 and the observation group 2 (all P>0.05) at 1-week, 2-week and 3-week treatment, however, they were significantly reduced compared with the observation group 3 (all P<0.05). The JOA score in each group increased to different degrees at 1-week, 2-week and 3-week treatment compared with those before treatment (all P<0.01), there was no significant different between the observation group 1 and the observation group 2 (all P>0.05) at 1-week, 2-week and 3-week treatment, however, they were significantly increased compared with the observation group 3 at 3-week treatment (both P<0.05).
Conclusion:
Acupuncture once every day and once every 2 days in the treatment of lumbar disc herniation is equally effective, better than once every 3 days.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Interpretation of Confidence Intervals
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...
